A computer system with secured data paths consists of a main computer (20) with a main processor (22), associated main memory (24), main input/output devices, and main data paths (28) interconnecting the main processor, main memory, and main input/output devices; a security computer (30) with a security processor (32), security memory (34), an operator console, and security data paths (38), connected to the main data paths of the main computer so as to intercept all data flowing along the main data paths; and a test computer (40) with a test processor, test memory, test input/output devices, and test data paths, connected to the security computer. The main computer executes user programs, the security computer executes security programs, and the test computer test-executes user programs.
